FUEL-MAGAZINE FOR STEAM-GENERATORS.

SPECIFICATION forming part of Letters Patent No. 285,828, dated October2, 1883'.

Application filed July 5., 1883. (No model.)

Be it known that I, GEORGE MIJHRING, o the city of Chicago, county ofCook, and State of Illinois, have invented new and useful Iinprovementsin Fuel-liIagazines for Steam-Generators, of which the following is aspecification, reference being had to the accompanying drawings,illustrating the inventi on i n whi ch Figure 1 is a longitudinalvertical sectional elevation of a steam heating apparatus embodying myinvention. Fig. 2 is an enlarged elevation of of the upper portion ofthe improved magazine removed from the other parts; Fig. 3, a top orplan View of the magazine.

My invention relates to an improvement in magazines forsteanrgenerators, and in combination of this improved magazine with thefire-box or locomotive pattern of boiler. The utility of fuel-magazinesbeing a recognized fact, it is unnecessary to enumerate any advantages,except with reference to the novel construction of my improvement.

In the drawings, A is the boiler; B, the niasonry surrounding the same;G, the exterior smoke-chamber; D, thehorizontal smoke-fines; E, thefire-box; and F is the crown-sheet, and G is the wagon-top sheet, of anordinarysteam heating apparatus well known to the art.

H represents a substantial wrought-iron cylinder, which is riveted tothe wagon-top sheet G and the crown-sheet F, forming a brace of properstrength for staying these two sheets, without the use of so manystay-rods or other devices as are employed in the ordinary construction.This cylinder forms one of the elements of my invention.

I represents an adjustable annular fuel magazine or reservoir, which ismade of wroughtiron, with a cast-iron ring, J, rivetedon at the top, anda castiron nozzle, L, riveted onat the bottom. The ring J is formed in asingle casting,with a flange, J, which is faced on its under side toform a close joint with the top of an annular cast-iron ring, K, whichsupports the magazine I. This ring is provided with an annular groove toreceive the projection formed bythe riveting together of the edges ofthe cylinder H and the wagon-top G. The ring K is secured in place bybolts 1), put through lugs d on its periphery and screwed into thewagon-top sheet G. The nozzle L is made in the form of an invertedtruncated cone, and it is provided near its top with an exteriortopfaced flange, a, which strikes a tight joint with that portion of theunder side of 55.

the ring K shown at 6 whenever the magazine is raised for the purpose ofproviding a space for cleaning the tines I), and thus preventing theescape of gases into the boiler-room. The

magazine-cot'er is shown at M, and it is pivis'provided with a similarcover and nozzle,

but it has no distinct ring and flange J J, neither the ring a, whichenables my device to beelevated by means of a branch chain, I, attachedto the flange J and drawn over pulleys Q by any suitable power. \Vhen itis known that a large majority of boilers will not admit of beingcleaned from their front ends, in view of the position in which they areset with a stationary magazine in front, the advantages of the presentimprovement will be apparent, and

be further understood when it is known th: t;

.where stationary magazines are used, anthracite coal has to be used asfuel, at an extra cost, because of the stoppage of the lines by the useof bituminous coal, the soot from which cannot be reached because of thestationary generator-magazine, and as a result the boiler has to bestripped, involving expense, loss of time, and great inconvenience. Bythe combination of the adjustable magazine with the ordinary filG-bOXboiler in the manner described these foregoing objections are removed,saving much time and care on the part of the operator.

Vhat I claim as my invention is- 1. An annular adjustable fuel-magazinefor steam lieatingboilers, consisting of a wroughtiron cylinder, I,witha cast-iron ring, J, and flange J, attached to its upper end, and aringor flange, a, attached to the upper end of the nozzle L, ring a beingfaced, in combination with the ring K, faeed at e, to form a joint by 2ass,

its contact with the ring a, and faced on its ber wholly exterior upperside to form a joint with the faced under side of the flange J on thering J 2. In a fire-box boiler for steam heating, the combination of awrought-iron cylinder, uniting the Wagon-top and crown sheets, andhaving at its topa fixed ring, with an adjustable fuel-magazine, I, which extends through the wrought-iron cylinder H, and from which it ishoisted by chain and pulleys to enable the boiler-fines D to be cleaned,as specified.

3. The combination in a steam heating apparatus, of a fire-box boiler,the Wrought-iron 7 cylinder H, and fixed ring K at the top of the same,with an annular adjustable fuel-1n agazine, I, the horizontal tubesD forthe passage of the products of combustion, and a smoke-chainto the saidboiler, as specified.

4. The combination, in a steam heating apcylinder connecting the wagontop G and crown-sheets F, the adjustable magazine I, the faced flange Jon the ring J the annular cast iron fixed ring K, supporting themagazine, the cast-iron nozzle L, having a fixed ring, a, to prevent theescape of gas, the buttons 0, the chain P, pulleys Q, the horizontalflues D, and the exterior smoke-chamber, O, constructed to operate asand for the purpose set forth.

, GEORGE MEHRING.
